Templates for Alerts

Hello, i’ve been facing some issues making templates for alerts, i need to deploy alerting tools for almost 50 clusters, i don’t really know what should be the best approach, at the moment i’m thinking of making a pannel for each one, obviously i don’t see it as the most convenient option but i need to know if it’s the only possible thing to do. Also, gauge visualization isn’t avaiable for alerts, i’m wrong? Thank you
